The Philadelphia Mint hasn't produced silver coinage for circulation since 1964. A 2003-P state quarter is worth 25 cents.
Neither the US nor Canada have struck circulating silver coins since the 1960s. If your coin is a collector's issue such as a US Prestige Proof, please post a new, separate question with more details.
The U.S. Mint has never made a $10 silver coin. If you are asking about NORFED silver rounds, they are not genuine United States Mint bullion coins and they are not legal tender. The value is only for the silver they contain.
The coin can't be solid copper. From 1965 to date all quarters are made from a copper-nickel sandwich composition. If it's a dark color, it's likely been exposed to some chemical that has corroded it. Take it to a coin dealer for an assessment.
It's from a set of ordinary quarters that were plated by a private company and sold at high markups as so-called "collectibles". Unfortunately there's almost no secondary market for these items, which means it's really just a copper-nickel coin with a thin plating of gold worth a couple of cents.
If it is one of the gold plated versions sold as a "collectable", these are still available from the manufacturer and only worth their retail price of $2 to $3 and only if it is still mint in the case and uncirculated. These were (and continue to be) manufactured by a third party vendor that simply takes quarters and electroplates them for resale. If it is out of the case or damaged, it's worth twenty five cents plus whatever weight in gold you can scrape off and sell for scrap (generally a few cents worth). If it still looks good but is out of the case, its worth maybe $1 if you can find a buyer If it is a solid gold coin, these are worth current market value of the gold in them. These were just stamped pieces of gold and intended to be used the same as a gold ingot, their value is the gold itself and not the coinage. This could easily be worth a few hundred (or more) depending on the type of gold used (14k, 18k, 24, etc) and the total weight (even minor differences in the carving or scratches can change the weight).
